"The Mahajjātakamāla was composed in late medieval Nepal (fourteenth to seventeenth centuries C.E.); half of its contents paraphrase an earlier Mahāyāna sūtra, the Karuṇapunḍarīka Sūtra. It has been edited by Michael Hahn." (Reikho Ohnuma, Head Eyes, Flesh and Blood, p. 288) Also see SAMHiTA on Bṛhat jātaka. This text is written in verse śloka form, and the jātaka genre of literature usually recounts previous lives of the Buddha.
